Thanks for the reply!

I've considered getting an Orange Rocker 30w combo but when I played it in store, it frustratingly did not sound like my head...

Plus the cost of replacing the Orange side (while still having to replace the randall side) is a lot more than I care to spend as the randall combo can not be made into a head...

The Orange Head is not the issue. The most weight and space is taken up by the randall by far. My band has banked on enough room for my Orange Head and a small 2X12 cab (and then a very small space for something else, so... the small head) in the van, in fact every member gets the same space.

While on the subject, anyone have any idea how to possibly make a switch which controls whether or not my amp is a 2X12 or two 1X12's in the same box?

Why, Hello forum!

For the last 3 years, I've been running two amps in my rig. They sounds sexy in conjunction but as my band begins to tour and play shows further and further away, I'm beginning to feel like my two amps take up to much room.

My current set up is an Orange 30W head on an orange 1X12 cab and a Randall 100SC (2X12 cab).

The main issue is with the Randall. Its too heavy. I'm considering buying an unloaded 2X12 and putting the Orange speaker in one side and a Randall in the other, affectively making two 1X12's in the same box.

But I need a small, powerful head. Any suggestions?

I'm hoping to find one with a graphic eq and/or a DI. If thats not possible, a nice line out would be appreciated.

I have to say I'm a bit sus about this arrangement - it has a fair bit of potential to cause you all sorts of problems such as earth loops and anti-phase problems. You certainly need an amp of your own, but your signal routing may also need some attention.

The ABY at the beginning of my set up is a Radial Twin City with 180˚ polarity switch, which I can use to set the phase right?

The Radial website says:
"To eliminate hum and buzz from ground loops, the Twin-City is equipped with an isolation transformer on output B. This is augmented with a ground lift switch and 180º polarity reverse switch that ensures both amplifiers play in phase while noise is reduced to an absolute minimum even when using older vintage amps that are generally more prone to noise. As a buffer, the Twin-City lowers the impedance and susceptibility to noise, making it the ideal signal driver for large stages when using long cable runs."

Could this help in the issues with earth-loops as well?

Sorry, I'm still a bit new to this so I don't know if I've already been taking steps in that direction so far or not. I've been fighting with this set up for about 5 months now so I've been trying a lot of different set ups and this one seems to work the best so far.

Also, I wouldn't be using my headphone jack, I was just trying to figure out if the fact I could hear myself without an amp through my mix board, in this case with my headphones, does that mean there's a preamp. I did, however, find my answer to that after I asked it... I never even though to google if a mix board could be use as a preamp, which it can. So, it is a preamp... So!!! I'm leave wondering the same as polo16mi:

So.... LM3886 GGG  is #1 candidate for our friend?

IS IT? I really want to start!

And Thanks for the advice!  :tu:

I'm trying to making amp that I can hook up to a 1X12 cab.

I'm running my guitar into a pedal board which splits my signal into two (well actually four, 3 going to the peavey and 1 into the orange) then into a mixer then out of the mixer (using the left and right as output 1 and 2). My Primary amp is an Orange and my secondary is a Peavey, but the peavey isn't loud enough so i want to build an amp to replace it.

What I was saying before is that I don't understand much about amps and preamps, but I know that when I plug my headphones directly into the mixer and play I can hear the as guitar clearly as I need, does that mean I already have the preamp you speak of?

You will need a preamp, but i guess that you can start using some of your pedals as it.

Preamp? How so? I'm running it through a mixer, and I can already hear it straight through the board's phone's so am I right in that assuming is something already doing the job?

Hey Forum!

I'm new to the forum but not to electronics (I'd say novice), I've built a guitar and a few pedals, but recently I've run into a snag.

I'm using a Bass Peavey Amp as my secondary in my Wall-O-Sound set up, but two things suck about it, 1: It's not mine and 2: It's not loud enough sometimes. Though the members in my band think I'm nuts, I'm pretty sure its an issue with the amp, every once in a while, it'll crap-out and go quieter. It isn't an issue when I'm practicing but at shows its annoying. The only thing I can do is boost it on the mixer I'm using but that only boosts the signal, and with a noisy signal its hard to find a balance between noise and usable signal.

All I want is something with a volume knob that I can hook up to a 12" 8ohm speaker. It doesn't even have to be that clean if it can get loud. It has to compliment an Orange Rocker 30w Head on a 1X12 cab.

I need a schematic and... hell, well, Idea's! I'm new to the amp end of this.

Please Help!
