i have a sansamp para driver for sale, almost the same as the bass driver DI but with a sweepable mid, good for both guitar and bass (i tried). You can use it as either a tone shaper, DI box and overdrive/distortion pedal all in one. It has a really gritty overdriven tube sound, great for metal/rock.

I'm selling as i'm happy with the sound my amp provides and this isn't needed. It's in as new condition, and i'm asking £120 posted. This retails at £200 brand new, so i think that's fair.

Here's a photo:
now on ebay, do a quick search for it

I ship worldwide but i'm based in the UK, at a bit of a bargain price right now too.
