Transmit Pre-Amp

From the vendor

The greatest pre-amp-in-a-box ever? Well, it's pretty good, so let's go with that.

Based on the broadcasting consoles from the 60's, this pedal offers a huge range of tones across it's two gain channels - both of which are internally tweakable so you get your own perfect combination of high and low.

It combines silicon and germanium transistors in a class-A configuration, offering excellent response and dynamics across the gain range. Add to that a transformer at the output for extra saturation at higher gains and you're onto a winner.

No fancy tone section here, as it aims to be 'transparent', but there is a bass-cut control to get rid of any unwanted wool from your signal.

Optional internal charge pump to run at 24V from your 9V supply. Leave it out if you want to stick with 9V, include it along with a toggle switch to flip between 9V/24V operation, or include it without a switch to hardwire permanent 24V.

Comes with three daughterboards for the two footswitches and the transformer. Why the transformer? It's pretty hefty, and needs to be mounted below the level of the main PCB to get all this sweet goodness into a 1590BB because we care.

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