TB gravitates towards $300 pedals that don't exist anymore. Anyone have suggestions for something no bigger than a 1590B and less than $120 that does "is it on" grunt/growl with zero trace of fizziness for bass? Either it fits the sound, the budget and the board or just go direct with compressor/eq
For moderate bass drive the venerable "Tillman" FET preamp is pretty swell. That'll fit in a 1590A or something even smaller. No EQ of any kind though, if that matters. I haven't tried one on my new acoustic guitar yet, but I remember it working pretty well for the mag pickup on my friend's Gibson J-160 when we tried it a few years ago.
Personally, I tend to prefer parallel drive with a blend control.. Things can get complicated fast when going that route though.
Oh, and I did one WTHPF pedal build with a bit more gain at the front end, which does mild drive quite well, but it was a total PITA to fit everything in a Gorva C65, which is roughly comparable to a 125B. Since it has a variable LPF killing fizz is super easy. Josh Broughton's Resonant Filter EQ is on a similar page, for the most part.
