I have a couple of pedals for sale...
A Boss OC-3, lightly used. Where my obsession with Octave effects started. I have a lot of love for this pedal - it's worth it for the Poly Mode alone in my eyes, it gives a really creamy, warm Octave sound which is why I've held on to it for so long...but, a boss SY-1 is now calling me so something has to go! £75 + postage.
I also have a Wee Lush Shoegaze Looper for sale aswell! A pedal which is a turbocharger for your other pedals. Whatever is in the loop feeds back into itself using the on/off or momentary function. Great for creating fuzz swells or just straight up insanity. You can get some really trippy effects by using it with a modulation pedal, amongst others. £35 + postage.
