From the vendor

Everyone knows the Tube Screamer, right? Well, Jack Orman stripped away the buffers and got back to basics to create the Son of Screamer. Why? Not everyone likes buffers. Tweaks available to make it more bass friendly too.

Used as the basis of many a 'boutique' pedal, we have the options for a few variations: Forever, Forever Explosion and new for 2022, the very doomy Inquisitor. The latter is hard to tame, and will squeal at higher gain and tone settings. The designer's description of the original alludes to just such behaviour, so live with it or don't bother.

The standard version is availalble with parts to make it a bit more bass-friendly.

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, 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. Knobs are not included.

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

Inspired by: Tube Screamer / Eternity / Eternity Burst / Witch Burner
