I've been asked to write an article on a pedal mod that is focused on bass. Any ideas? Has to be targeted at a commercial pedal.
Input cap, coupling caps, and tonestack caps is what I consider "bare minimum" for an op-amp based circuit.If you change the input caps, wouldn’t you also need to increase all caps in the audio path I.e. coupling/output? Just letting bass in the front door may cause the circuit to overdrive more, but you will still remove the bass frequencies with every cap the signal encounters.
I found the one I used, it was Coda, though he says the mods actually came from Madbean. There's a section near the bottom "Using the Klon Centaur with a Bass".Retuning a Klon Klone for bass sounds like an interesting opportunity. Can anyone point me to some mods? I can make some up, but I'd rather see what others have tried first.
Aion has some bass modes for a Klon in his Refractor build docs.Retuning a Klon Klone for bass sounds like an interesting opportunity. Can anyone point me to some mods? I can make some up, but I'd rather see what others have tried first.
I really dig them, opens up the bottom nicely. Even on guitar I find the stock Klon to be a bit thin, I think the bass mods work well for guitar too.Cool, thanks. I ran across that same article in my search. Good stuff. How do you like the mods?
Grind Customs created a bass klon with a boost, it never left my pedal board. I really like it.Cool, thanks. I ran across that same article in my search. Good stuff. How do you like the mods?
Another good lead, thanks. Since the Klon's GAIN control doubles as a clean / dirty blend, it should be possible to rebalance the relative gains of the clean & dirty paths so that the clean channel is dominant over a larger range of the GAIN knob.Aion has some bass modes for a Klon in his Refractor build docs.
I'd like to see a clean blend circuit that had a boost stage for the clean signal. Basically a parallel split with a volume control on the clean for blending. The circuit I use currently is Barry's Buff-N-Blend. It works well most of the time but if the drive is much hotter than the clean, it loses it's usefulness. It be cool to know what blend circuit Aguilar uses on their bass offerings.
Now that you mention it, splitting the Gain pot would give the control I mentioned before. Too bad the Klon is such a boring drive, lol.Another good lead, thanks.

Not much change from a stock Klon. A boost was added, +18V rail deleted in favor of +9V, R11 increased to 1M and R3 added. No changes to the freq response, which is surprising.Grind Customs created a bass klon with a boost, it never left my pedal board. I really like it.
I built the VFE Merman (PedalPCB Sea Monk]. The split GAIN control is ok, but doesn't do all that much more that a ganged GAIN control. Because of the complicated network feeding the 3rd stage, there is a fair amount of interaction between the two halves of the GAIN control. Specifically, turning the CLEAN GAIN pot affects the DIRTY channel's equalization. There are some simple changes that strengthen the Clean channel and the Bass bleed. I definitely recommend building the Merman or Sea Monk if you want to experiment with Klon mods.Now that you mention it, splitting the Gain pot would give the control I mentioned before.
