Ampegulator - Ampeg Amp Tone Shaper

From the vendor

Drive pedal to get you that famous low-end growl of a cranked Ampeg. Designed primarily for bass, but sounds great on guitar if you're after rich, roaring bottom end - fantastic on drop-tuned stuff. Baxandall tone stack for a huge range of sounds. After hearing great things about this circuit when ran at 18V we decided to include an optional onboard charge pump to get you that extra juice from your standard supply. Those V's really open this thing up - tons of headroom and extra oomph. You can opt to wire it permanently at 18V, or switch between 9/18V operation with an internal slide switch or external toggle switch. The difference in sound is quite marked, so its well worth having the external option. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. You also have the option to replace the stock linear Gain pot with a reverse log, which gives much more control. Not a cheap kit, but the circuit requires eight 2N5457, which are getting harder to source and more expensive by the day. 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, 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 available as an option with full kits, and will not take a battery. Knobs are not included. Builds are only available with full kits including enclosures and vertical-mount pots. Please choose appropriate knobs.
