Product update!  All SD-1ge 5 star Super Overdrive pedals shipping from now on do NOT have the Burr Brown chip installed.  Instead they get two stacked TI RC4558P chips operating in parallel, which reduces the noise and improves the sound even further than the previous models.  The BB chip is no longer included with SD-1s.

If you have any questions about this or any other feature of our pedals please get in touch by email to info@robertkeeley.co.uk or phone to +44 (0)1223 841035.

All TS808-TB true bypass pedals shipping from now on will get a 1982 vintage JRC4558D chip fitted as standard.  This used to be an optional extra but we're now including it in the top model at no extra charge.
