Yeti (although I'm sure the bass and guitar thing cuts out quite a few contenders on its own).
Most of them! It was a interesting experiment - useful for me - not sure about anyone else though. I'm very familiar with my strat and bass clean tones, I play mostly clean(er) tones these days - the original thinking was to experiment with buffer(s) and preamp(s) - but external to my bass/guitar - active basses/guitars are not my thing for day to day use. So wasn't specifically looking for a down 'n dirty drive - but more of a something that would be a bit like raising the pickups - but in a pedal.
Yeti I'd be interested to find out what that dry/wet blend does in the electronics.
It was kinda explained to me - alas, I'm not the keenest student of what the internals were doing. IIRC there's two sides to the circuit, the 808 (TS) opamp and the clean boost which - at some point - are blended together - that's about as much as I (inaccurately) recall. A bit of googling dug up some 'sprinkle drive' schematics and something called a 'axe grinder' (TS w/blend). Sure you';d understand the schematics - it just gives me a sore head.
Yeti You mentioned that you had tried a DIY klon... out of interest, what was it that didn't work for you?
The Pop effects one was good - no complaints on guitar. Think it worked fine on bass too. The fellow junkie's build was unreliable - so tough to say on that one. Either it kept breaking, coloured EQ or overly compressed dynamics as he went though versions.
After trying the sparkle drive, I took a break from pedals. But it got me thinking about gain staging again - so was useful. I've done some re-wiring on the bass recently, which turned out really well ( 250k pots -> 500k and a wee tweak to the wiring) so it's a good time to re-visit the experiment...waiting on some fresh strings to arrive from Jhb so I can redo the setup and dial it in again.
One thing I REALLLLLLY liked about the dry/wet blend was that it felt like I could dial in a little bit of pick attack with the dry signal - not at all desirable for higher gain (to shreddy style) tones, but added something dynamically for me to the cleaner/breakup tones. At times, I do like to dig in with a stiff pick, so perhaps it's just something that I particularly liked. It just felt natural to me. If that makes any sense.
