Zoom PD-01 Power Drive. No longer made, completely analogue and reasonably cheap. I recently got another Guild Starfire III as I had foolishly sold my first. As I like to do on a lazy Sunday afternoon I tried it with all of my different OD pedals to see which was a good match with the guitar and my Tweed Twin clone, as this amp goes beautifully with this guitar. Well I tried my all-time fave, my Bad Cat Two-tone and sure enough it sounds fantastic. Then I try it with a Menatone Working Man's Blue and VOS, an Xotic BB, a Timmy, a Lovepedal Eternity and a BYOC TS. Well I just can't believe how good the Zoom PD-01 sounds with this combo. With bass on full and treble at around 11.00 I can get the guitar to sound almost exactly how it does with no pedal but with a lovely singing crunch that it very touch senstive and chirpy. The Menatones which sound so good with a Gretsch or 335 sound slightly artificial by comparison. The Timmy sounds pretty ordinary with this combo where it sounds so good with other guitars and amps. So I guess it tells me two things - one is that the PD-01 is a better pedal than most tone snobs would give it credit for. I kinda already knew that! And secondly not all pedals work with all guitars and amps. I am amazed it the quality of sound I am getting from the Guild (also criminally under-rated!), the PD-01 and my lo-po Twin. I also have the Zoom Ultra Fuzz that they released at the same time and it's my favourite fuzz pedal. I wish that they'd pursued thses types of pedals more because they are both excellent pedals and the rest of the Zoom stuff totally leaves me cold!
