Rodent Baxandall

From the vendor

The Rat. What's not to love? Well, maybe the fairly limited scope of the tone control. Help is at hand...

We've kicked the tone into touch and brought in a two-band Baxandall tone stack so you can tweak and tweak and... (OK, technically it's a James stack as it's passive, but everyone calls it Baxandall - you know what it is). Available tuned for standard guitar, using the stack values from the Catalinbread Manx Loaghtan, or a more bass and drop-tune friendly version based on a boutique box that definitely doesn't blow.

All that Bax action takes a toll on the signal level, so we've given you the option of building it with the normal Rat buffer on the output, which will reach unity at around 1-2 o'clock, or going for a much better speaker-worryingly-awesome FET boost configuration.

Hmm, what else... How about a second set of clipping diodes so you can toggle between two flavours? We'll supply 1N4148 (Classic) and red LEDs (Turbo) with the kits anyway, you just need to select the addiitonal toggle switch. Add a pair of BAT46 diodes to the mix if you want to go for the 'You Dirty' option - note, this was originally germaniums but the BAT clip identically.

Kit is supplied with OP07. Our stash of vintage LM308 is gone.

Optional trimmer for the ruez 'Response' control mod.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components (depending on selected options), pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is only available with full kits, and will not take a battery. Knobs are not included.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
