Ibanez TS-808 Tube Screamer Reissue Switch Repair.

The Ibanez TS-808 Tube Screamer is, rightly, regarded as a classic pedal, and has been reissued by Ibanez; this is lucky as an original TS-808s will set you back several hundred pounds.     Unfortunately the switches on the reissue (and indeed the originals), are not that robust. This pedal came in with a broken […]

Ibanez Tube Screamer TS9 DX Repair

Here’s an Ibanez TS9DX Turbo Tube Screamer we’ve just repaired.     The pedal came in with a common fault: the switching was intermittent. This is usually due to the foot switch wearing out, however the foot switch in this pedal was fine. After some prodding with a high tech implement (a chopstick!) I found […]

Two EH Memory Man Deluxe in for Repair at JPF Amps

Here are a couple of Electro Harmonix Memory Man Deluxe delay pedals we’ve had in for repair.       The pedal in the right was distorting badly with an ES-335 when set to unity gain; a problem with the Memory Man is that they don’t like hot guitar signals. This can be reduced somewhat by […]

These are rare and valuable pedals.     The Dopplerganger is a phase/ vibrato pedal with 2 low frequency oscillators and is a particular favourite of mine. The Meatball is an envelope filter, and the Ring Stinger is a ring modulator (which I would have […]

Boss Pedal Repair at JPF Amps London Workshop

Here are 3 Boss pedals I’ve had in for repair at our workshop; a DM-2 analogue delay, an OS-2 overdrive /distortion pedal, and a DD-3 digital delay.     Boss pedals are, in my experience, very reliable. None of these pedals had major faults. The DM-2 (which for the uber pedal geeks was the earlier […]

Boss TR-2 effects pedal repair and modification

As well as repairing guitar amplifiers, we also repair and modify effects pedals. The Boss TR-2 is a good sounding tremolo pedal, but suffers from a loss of volume when the effect is engaged. This is easily cured by changing R9 on the PCB from 10k to a lower value. I find 6k8 works well. […]
