Quiet Boost

From the vendor

If you love a Super Hard-On but think the crackle is not ok, look no further. Despite the name, this babe is anything but quiet. It'll knock your speaker out given half a chance. All the oomph of the SHO but with no biasing crackle from the FET. Sweet! Push your amp into submission. Note: The level on this effect goes from just above unity up to outrageous - there is no turning it down below unity. Board-mounted pot for minimal wiring and easy mounting in the enclosure. Kit is available with a standard sized 1590B enclosure with battery, or a mini 1590A (36 x 90mm) enclosure with DC power only, though be aware that you'll be wiring in a very confined space. 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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls, in a 1590B. 1590A will not take a battery. Knobs are not included. Builds are only available with full kits including enclosure. Please choose appropriate knobs. Inspired by: Crackle NOT O.K. Boost Difficulty: Easy PCB size: 25 x 22mm Knobs required: 1 Enclosure: 1590B, 1590A Direct Connect compatible (4 way) Download INSTRUCTION PDF
