  • Ampeg Echo Twin

    Has anyone played one of these? I read that Frampton was nuts about them. I was trying to do more with less on a new design, and was curious about the reverb fold-back technique. It seems feasable to drive the tank from the OT. The idea that it feeds back into itself could be interesting too, maybe a little echo-y? I've also read that performance is subpar, but is that an evaluation from a surfer? I like just enough reverb to add a little air to the tail of notes, and seldom, if ever, dive into the Heavy Surf. You don't have to flame the reverb if you don't like them, but I'm still interested in comments if anyone likes as little reverb as I do.

    Wow...Tough crowd

    I guess no one is a fan of the fold-back reverb. It isn't for everyone, but I guess 'good' and 'bad' are subjective things anyway. I'm taking two weeks off over the Holiday, so I may have time to see if this is good for anything. As a baseline, I could connect it to a Champ output and return the signal to the volume wiper through a Reverb pot. One of the London Power books has some design guidlines to prevent blowing out the reverb tank. I'll post what I find, 'good' or 'bad'. If it doesn't suck, I'll see if it fares as well on a bigger amp.

      I fixed one last year. One of the output transformers was partially shot. It worked, but sounded awful until that tranny was changed out.
      The reverb was the same as any other amp reverb in that wattage range. That amp has 2 discrete amplifiers in it. an awful lot of weight and cost for very little special sound. Trem was OK.
      I can't say anything extra good or extra bad about it.

        Well....

        It may not have been an Echo Twin then. An amp in that power range (or not) using the output as the reverb driver is different than almost all amps. Extra iron for two outputs is necessary for stereo, which I also dig. There is considerable economy in tube usage having two channels, reverb and trem and using only (4) preamp tubes. I draw a little inspiration from that, but if it ain't special, then so what, right? I'm still curious to hear a reverb done in that fashion due to it's economy. Since I'm just looking for a little wash in the background, I'll just have to try it and hear for myself.

          come to think of it...

          You said, "The reverb was the same as any other amp reverb in that wattage range." That may well be a compliment to the reverb if you thought it sounded the same as any other small P-P amp. I'm thinking that if you didn't like it, that may have come to mind first. Hmmm... now I'm real curious. Thanks for the comments.

            The amp I mentioned is pictured in this link...not the actual amp I repaired, but it absolutely was this model:

            The switching configurations were quite interesting, unlike any other guitar amp I've encountered.
