From the vendor
An attempt to recreate the Fender Blackface trem in a box. Does a pretty good job too.
The original has a footswitch to swap between the two speed modes, but really - what're the chances you're going to have a single speed setting witih both switch positions working out for you? It's a toggle. If you want to wire it up as a footswitch, go nuts.
We've made a couple of value tweaks from the orignal to mitigate the volume drop and the all-but-useless depth control.
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.
Inspired by: Swamp Thang
Difficulty: Medium
PCB size: 50 x 3mm
Knobs required: 2
Enclosure: 1590B
Direct-Connect compatible (4-way)
If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability.
