So finally got time to reshuffle and with a bit of Jiggery pockery, managed to fit another pedal on the board.
So in the synth loop, after the Frantabit I have put a
Copilot Orbit - Frequency Modulated Fuzz- An outrageously cool pedal which has 2 sections and a blend to move between them. On the left is a Gated fuzz, in the vein of a Mastatron/Wooly Mammoth. The right hand side has a VCO/ Ring Modulator, which just makes these mad, synthy laser gun sounds, which can also be controlled with an Expression pedal (must get one, no two). This version appears to have been modded with a clean blend, although I don't use it as not needed.
