As New Boss SD-1 with either the Dexter Mods TS-9 or TS-808 conversion kit installed, comes complete with box and manuals etc

Check my feedback for this mod:

"The TS9 + gain mod is outstanding. Used as a boost the 'muddy' and mostly unused neck pick up on my vintage Maton responds with beautifully clear notes while retaining its warmth. Very nice!!" deano25 SD-1 w/TS-9 mod, auction #253281101

The Boss SD1 is a take on the Ibanez Tubescreamer but has a slightly different circuit components and a different clipping design.

You can add options like switchable clipping and higher/less gain switches if you want so feel free to discuss those via Q&A.

The mod consists of restructuring the clipping section from asymmetrical clipping to symmetrical clipping and replacing the out of spec Boss components with TS-9 or 808 spec components.

The stock, and noisier, JRC4558DD op amp has been removed and in it's place an 8 pin socket has been installed. In the socket I've slotted a JRC4558D op amp and the auction includes a 4558P op amp as used on SRV's Tubescreamers.

You can swap op amps to the one you prefer by simply opening the pedal and removing the 4558D op amp and slotting the 4558P into the socket.

The mod includes a Green LED.

This pedal is used and comes with it's original packaging, including box and owners manuals etc, and it sounds great.

The mod is guaranteed. If there are any problems when you receive the pedal simply return to me, I'll service it and send it back.
