wateroftyne Posted March 30, 2016 Share Posted March 30, 2016 Hey gang On the assumption it's well implemented, how practical is the James / Baxandall tone stack for a bass head? I know there's only a bass and a treble knob, and you can 'boost' the mids by rolling them both off and increasing the gain. How useable is it in the real world? Any experience...? Pros, cons? Thanks, all! Quote Link to comment Share on other sites More sharing options...
Dood Posted March 30, 2016 Share Posted March 30, 2016 (edited) I really like the Baxandall circuit as it is a shelving type I believe, meaning that you can choose a corner frequency and then everything below it (or above in the case of the treble control) gets boosted (or cut for that matter). I think as long as you choose the frequencies carefully then there's no reason why it can't work. My first bass preamps I built used Baxandall circuits and at the time I didn't miss the mids. Of course, it wouldn't hurt to create a circuit to daisy chain, a semi-parametric mid frequency control I think would be a valuable inclusion.

tauzero Posted March 30, 2016 Share Posted March 30, 2016 I imagine it's what's used in 2-band EQs for active basses, and you'll find it in a lot of hi-fi amps. Simple circuit, low component count, just needs a 3x gain (IIRC) to bring the output level up to the input level. Quote Link to comment Share on other sites More sharing options...
wateroftyne Posted March 31, 2016 Author Share Posted March 31, 2016 Cheers, folks. A quick bump for any more input (pun not intended)... Quote Link to comment Share on other sites More sharing options...
Beer of the Bass Posted March 31, 2016 Share Posted March 31, 2016 (edited) I like the James tone stack, and I reckon it can do almost everything a three knob fender tone stack does. I had a four channel Carlsbro valve head where I changed one channel to a fender tone stack and left the James stack in the other three. I ended up using the first channel less than the others. You don't get any particularly sophisticated midrange shaping - it's quite a broad-brush approach to EQ, but can sound good. It's also possible to mod them with a pot to shift the range of the whole circuit up or down and a switch to add a mid bump without turning down the bass and treble. I intend to play around with these options some time... Edited March 31, 2016 by Beer of the Bass Quote Link to comment Share on other sites More sharing options...
