Thankyou for your input

Yeah the rehousing project does seem like it would be quite a mission to complete, but I also enjoy doing projects like that.
I will try your suggestion of running the Laney with it's power amp through the Peavey's speaker though.

The Laney seems very old, if you looked at the thread I linked at the top of this one you can see the condition I got it in. That's why the tone pots are so scratchy, it's not my fault, I actually look after my gear haha

My old school is upgrading their hall at the end of the year and because I'm still in contact with my old music teacher, she said once they have finished and all the gear their not using any more is sorted out I'm welcome to whatever I want that is either broken or not being used. I'm hoping to obtain a rack microphone stereo power amp that I saw sitting in the corner last year not being used, and hopefully convert it from mic input to guitar input... and make the necessary adjustments. That way I should be able to run my setup in stereo and finally take advantage of stereo chorus, phaser, delay etc from my tc electronics g major

The goal of this project was to get the Pre amp out of the Laney and into my rack, at the end of the year clean up, convert and fit the power amp into my rack and then take the speakers out of my Laney and make a 2 x 12" stereo cab...

As you can tell I'm obsessed with racks... and also a wishful thinker there's no guarantee I'll get that power amp...

I agree, I've never liked the Bandit on it's own, I noticed that it's very bassy. That's why I've been using it's power amp with my v-amp pro. But seriously when I hooked up that Laney preamp to my bandits power amp, it was sooo nice to play. It doesn't really make sense but I swear my v-amp must have latency issues or something because my guitar just felt so responsive!


EDIT!!!

I just got home from my university audition for bachelor of popular music, It went great! Hope i get in!! Just excited I didn't have to say that haha

Ok back to the project, I decided to pull the brains of the laney out and have a look, it's quite wide, wider then a 19" rack that I want to make it...

Here's a few pictures of it, there's a tag that says "DAVE 14 JUNE 90" so I'm guessing someone called dave either serviced it or built it in 14th of June 1990?

FRONT

TOP

Front Circuit

Back Circuit


Now here's my questions

Do you think I could cut the circuit board between channel 1 and 2 and reconnect the the board with wires and then in the rack unit put the second channel below the first?

Secondly the back circuit looks to be the power amp section, but the front circuit board connects to it with 6 wires (red) starting to wonder whether it would be easier to mount the full unit, preamp and power amp in the rack unit and then just have pre amp output? not exactly what I had in mind and the power amp wont be used but anyway what do you guys think?

Hey guys! It's been a long time since I was on here! But I think you guys will help a lot more then UG... Last time I posted there they told me "sell everything and buy a decent amp"...
You might remember me from this post http://www.ssguitar.com/index.php?topic=1785.0

Ok well here's my current gear...



My current setup is LTD kh-202 into akg wireless into behringer v-amp pro send g major send v-amp pro into peavey bandits power map input all controlled by fcb1010 midi controller

The v-amp seems to suck my tone, and do horrible things to it, my guitar has almost no sustain and just doesnt sound "real" enough to me... So I decided I would try plugging my guitar directly into my Laney PL100 Twin which has terrible tone pots that are scratchy and sounds really trebly as an amp... but then I ran out the "send" of that amp and into the "power amp in" of my peavey bandit and I was shocked... It sounded like a real guitar! nice and crunchy on the dirty channel and really nice cleans. The response of my guitar was so nice! Playing fast, sweeping etc just felt like it was instant, I guess with the v-amp there must have been latency issues? :s

Here's a picture of the laney after I refurbished it all and replaced the writing on the front:

But the whole point of this thread is to ask, how plausible is it to take the laney's preamp out of the amp and mount it into a rack unit? I'm good with electronics as long as I'm not starting from scratch, I can modify things quite well. I would replace all the pots with new ones (how do I go about finding out what rating each pot is?) and replace all the input and output jacks. I haven't taken the laney apart in a long time and I have no photos of the inside but I will probably do that tomorrow and post it here I hope it would fit in a standard rack unit either single or double in height...

Then I'll take the v-amp out of my main rig and just use it for recording

Yeah I live in Australia and this is a Laney amp, not Peavey. Its a pull knob to activate "bright" on the second channels gain, which I don't intend to use, at the moment I just push the shaft in and turn it, it works but it falls out easily, I will replace all the bad knobs eventually just have so many side projects going its crazy...

Oh I forgot to mention a few of the pots have a pull option that turns on whatever it says such as "pull full" on the treble pot. When removing the knobs I accidentally pulled out the whole shaft... and I dont know how to fix it...

Ok thanks guys
The pots are ok when I get them where I want them but there just scratchy to turn, I'll try cleaning them soon

Hey guys

My school had this old amp that was never used and well I talked my way into them giving it to me
When I got it, it was in terrible shape, the front grill was all bent and a spider was in it :/ and the whole thing was rusty, see below



So I went ahead and took it apart, straightened the front grill out, removed the spider... lol, and the front panel, all the knob details were coming off so I designed an entirely new layout on Photoshop, printed it on 3 pieces of paper, cut them out, and sanded back the panel. Put a coat of acrylic lacquer on the panel, placed the paper where it had to go, the lacquer acting as a glue, then lacquered over it about 5 or 6 times, letting it dry in between then let it dry for a few hours. At the same time sanded back the grill and the speaker holders underneath it and they got a fresh spray of black paint. I re wired the speakers also with home theater system cutoffs dad found at work. I also hand brushed every screw on the amp at least 6 times to get a decent coat of paint on them as well.

Heres what it looks like now -



As you can see it came out a hell of a lot better, but I have one problem, a lot of the pots are scratchy when I turn them, how can I clean pots? other than that the amp is awesome and has currently replaced my Peavey Bandit 112 as my main amp

Hey guys!

I'm sorry if this is in the wrong section, I couldn't decide where it belong, if anywhere... I know this is an amp forum but you guys were such great help when I needed it that I thought you guys could please help again.

Anyway to the point... I use a distortion pedal for my dirty tone and I have a TC Electronics G Major for my effects. I cant afford a midi controller so instead I'm using the external control input of the G Major with a keyboards momentary switch to switch between two groups of effects for clean and dirty tones. So obviously my problem here is I need to press 2 pedals at once (Distortion and Momentary) to get my desired clean and dirty tones.

My solution to this problem is, by using one of the G Majors built in relays, I can use it to switch on a bypass looper and then use the momentary switch to activate the relay. So I went ahead, bought 5 mono jacks, 2 LED's, a DC input jack and a DPDT Relay. This worked, however I never added an on/off switch. So I sat down and thought of what else I could add to this. I decided I want a on/off LED, 2 inputs that are chosen by a switch - each with an LED (I want two inputs - one on the back and one of the front - so I can connect one to my wireless and have one on the front for if I want to plug straight in, this box comes first in my effects chain) and finally an LED for either loop on or Bypassed. So enough of my rambling, I drew up a schematic and wanted to check with you guys whether it looks correct and whether anything in it is overkill such as the DPDT relay that controls which input is active, could I just use a toggle switch or is a relay going to give a better connection?

Oh one last thing... what resistor's should Blue LED's have to run off 9v and not be blinding? on my original simple bypass looper the LED were so bright they lit up my room with the light off...

Here's the schematic I hand drew, hopefully nothings unclear on it, Its the first schematic I've drawn completely myself.



Thanks in advance for any help/feedback anyone may give

Thanks a bunch Also, are solder less breadboards a good idea? to start trying circuits out?

Wow, you've helped me so much, thanks so so so much for all your help salvaging sounds good, cheaper haha and the help with all the components, wow, just wow, I didn't realize there were so many different types of everything, anyway time to look for junk to salvage haha thanks again

Thanks heaps
I'm planning on making an order soon since all i got here at home is a bunch of resistors and LED's... lol.
I know I have been asking a lot but what extra values of transistors, capacitors, resistors, etc, should I buy to start "tinkering" with? I don't want to make an order and think, "I should have got some of those..."
Again, thank you so much you have been so much help

Another question sorry....

With that link you posted, Minion posted his pre amp, which you can see below:



Is this a full preamp? would I be able to use it to get a different sound? I'd be combining this with the distortion circuit and running it either straight into my Peavey Bandit 112 or into the Bandits power amp. Is it a decent amp? like are any of these DIY circuits going to compare to Peavey and Boss piece of equipment and give me a unique but still professional sounding sound? thanks again and remember I'm a newbie when it comes to audio electronics

Thank you And sorry for the dumb question I should have looked around better...

Sorry for another question but what kind of capacitors do I use? and whats the difference between capacitors? thanks

Thanks

I got heaps to read and do now, I just gotta buy myself a breadboard and some components and I can start trying some things

Hello

I found this schematic on the "diyaudio" forum and the guy who posted it "minion", in 2007, said he plays heavy metal and hardcore punk and this distortion suits the style perfectly, which is perfect for me since I'm in a hardcore metal/punk band. Also he states the orientation of the Transistors is reversed in the diagram....

Here's the diagram:


So even though some parts are hard to read I think I managed to draw up this schematic correctly?



What I don't understand is how distortion works, what this circuit is doing, whether this is actually a good design and how do the potentiometers work when there only at the input and outputs?

I intend to eventually learn how to build a full preamp, maybe with this circuit as its lead channel but for now this is my first audio based project so I should keep it at least a little simple

Any help would be greatly appreciated

EDIT: sorry if my schematic is hard to read... photobucket shrunk it down...
