I may have the break the habit of a lifetime and actually buy an effect pedal
Actually these kind of effects are the only ones that I don't mind buying now. You're not going to easily reproduce that sound with DIY so it gives you something a bit different to the usual boutique dirt pedals or PT2399 delays. Still over the last 5 years I think the only pedal I've bought was a Pitch Factor so it doesn't happen very often!
