G'day I love making up pedals, amps etc for my daughter and myself. My problem is that I can barely play guitar, and no way would I like to hear what I play. When I make up an Amp, like I am doing now, I would like some way of testing the sound, I would love it if someone who can play an electric or bass (or both) could record some dry tones and leave a recording that anyone can use. If I came up with the best pedal ever, and then plucked or strummed my cheap guitar it would sound like a dogs dinner and no-one would like the sound sample. Lets call it: Sample1-Chord set, Sample 2- Plucking etc. Or Sample 1- Stairway intro.... If we could all send the same signal into our gear and then post samples we might get a better understanding of what someone else has made. This makes sense to me, but I know bugger all about it really. Soo... Could someone who has the recording gear please make some test tracks up for me with a clean dry signal please.
Also while I am asking about this, what would be the best way to inject the signal, I can use a computer signal out, DVD player signal out, Phone (Windows . How much should I drop the signal from say a computer sound card to mimic a guitar out. 5 meg resistor with a 1 meg pot ? A small op-amp circuit for high Z ? All comments good and bad will be greatly appreciated, thank you Michael
Yeah, the input power to the amp is 150W, 240V here in Australia I haven't picked it up yet, I'm going into Hobart (Tassie) next week and I will pick it up then. It looks like I might have to trace the circuit myself when I get it. If I make a schematic up I will post it here. For $35 Au ($25 US) I think I can't loose even with a Gorilla Amp. The photo I posted is from the Auction House I got it from. It will entertain me for a day or two at least when I get it.
Thanks for that Enzo. I'm not sure if it is a small practice amp, it's over 100 Watts and has a 12" inch speaker from what I understand. But you might be right with the components, the Gorilla TC-35 has one Op-Amp and a TDA2030. I can't find much information on the TC-110 on the net, I was hoping someone here has some info on them. Maybe practice amps are bigger then I thought.
G'day everyone I think I just bought myself a Gorilla TC110 Amp on auction. I don't know why I did it, it just happened. I paid $35Au ($25 US) for it so I think I can't really loose anything. I believe these amps sound crap from what little I could find out on the net. Does anyone have any circuits or information on Gorilla Amps ? I read that Pignose made them. I will have to go and pick it up next week when I go to the city (Hobart Tas) If I'm lucky at least I scored a reverb tank, 6 knobs. a decent transformer, etc. I might stuff a 1 channel Sunn Beta pre-amp into the box, just to confuse people. Or maybe a Marshall Lead 12W reverb, with a nice celestion 12" speaker. A Schematic would be nice if someone has one.
This reminded me of this nice design I found ages ago, I have drawn up the way I thing he connected the transformers. I think its how Phatt ? said it was safer to do it. I think it has also been posted on FreeStompboxes at a later date.
Wondering if the 2.5Watt will be called Bumble Bee ? Then I can't wait for the Wasp and finally the Hornet. I might have to get a Jensen MOD 5" 30watt 8ohm Speaker in anticipation. Love the work Joecoolo85, keep it up. :dbtu: :dbtu: :dbtu:
That is a very good point Enzo Since I am not a musician, only a casual string plucker I would not know that. I guess if the stage has mains power at the front so you can power a pedal board from somewhere in front of you then you don't want any extra cables to trip on. I have only had a close view of people playing in clubs and pubs where the stage is very small. I have seen The Angels, Midnight Oil, AC/DC and many other acts on small stages where they hardly moved around. I guess I'm showing my age if I saw them on small stages early in their careers. I have seen ABBA busking in a park in Stockholm before they got famous too, (I was really young) I still think it would be feasible in small clubs and venues, or practice and home use. I brought it up mainly because the expense would be minimal if incorporated in the build, and good for beginners at least. It would also be one less item needed to buy, drag around etc. I like all the answers so far, informative. Michael
I guess I was thinking more for home use or practice. But if you consider that old style pedals only used around 4mA - 30mA each. That's about 30 pedals at under 1 Amp if you are using overdrives, wahs, chorus, phasers, big muffs etc. The 20ft cable going to my car trailer lights is smaller then a guitar cable, and brake light alone use 3.5 Amps. Speakers carry more amps then pedal boards, cable is not thick as a fire hose. Modern pedals can use a lot more, loopers and multi digital pedals can get close to 500mA, but how many use them ? I am just guessing as I just tinker with playing, and making pedals and amps for my daughter. I feel that 2 x 1.5A 9V outlets would be of use to a lot of people, but I know bugger all. I was mainly wondering what others thought, before I add it to my next amp. I feel that a 20 - 30 foot run should be ok if you start with 9.5V at the amp, good for 1 Amp with little loss with speaker cable. https://stinkfoot.se/power-list
I am wondering why Guitar Amps never have a 9V output on the back for pedals ? It would be really easy to include on a new build, and not very expensive. How easy to run a few pedals with a 9V output already there. Is there a reason I have never seen it done? For $10 you could have 4 x 9V 1.5A outlets on the back of an Amp. Most existing amps can probably have one added with the current transformer. I would love to know what others think of this. Is there a valid reason not to do it ? Michael.
The only tiny speakers I have ever noticed decent sound from are in soundbars or computer speakers, a very few of these sound ok, sort of. They are meant to be small with big sound, but I imagine they might sound crap if you take them out of the housing they are in. If you find some cheap at a tip shop or second hand shop it might be worth a try. I have a small sound bar on my computer which can get fairly loud, the speakers are very small in it, I'm sure I could drive it straight from a preamp pedal. I have a Sunn Beta Lead pedal I might try it with one day.
