Electro Harmonics LPB talk;
I have an original LPB-1 that I rehoused maybe 10 years ago. Didn't use it much since. I busted it out a few weeks ago and thought I must have done something wrong; the effect was very subtle and I remembered it being a huge volume/overdrive whomp when engaged. I picked up another old one for $55 and it's the same. Pleasant effect, for sure, but more of a warm overdrive. More pronounced with humbuckers than single coils. I've only tried it out on a Champ so far, so there might be something more revealed on a bigger amp, but I definitely didn't get the big volume blast I was expecting....
Over the weekend I tried both LPB-1s out on a Twin Reverb and...uh...yeah...that's the stuff. Huge boost. Sounds rad. One thing though, the one I rehoused worked fine. The one I picked up recently didn't change the signal at all when the slider switch was turned to boost. I did a little poking around and found that the switch itself is bad. No big deal. I bypassed it and the little circuit still blasts. I'll replace the 50 year old slider. But when I was initially trying these out on a Champ it sounded like they were both producing the exact same effect, which was to say very little effect. So much so that I couldn't tell that one was working and one was not. It totally makes sense that the effectiveness of the boost all depends on your amp and it's available headroom, but it's wild that the difference is so pronounced in practice. I love learning stuff like this. How things interact radically differently depending on so many aspects of your setup and signal chain. Anyway, I wanted to give an update. I'm on board with the Linear Power Booster again after a long time away.
