Surface Mount ICs

Upgrading opamps for better sound quality is very common request. The commonly used (and dirt cheap) JRC4558 may be popular for Tubescreamers but is not be ideal for circuits when you want the most transparent sound. Burr-Brown and other companies make excellent chips to retain sonic fidelity. Above is a photo of their surface mount chip which was used to upgrade the signal path in an EHX Holier Grail..

Monster Face "Organ"


I’m not sure what exactly inspired this, but it’s a 10 note sine wave generator giving you all sorts of beeps. The fun part is that each button’s frequency can be adjusted and playing more than one at a time gives entirely different frequencies. Videos to be posted when time permits. $150.

Setting Saver knobs

Over the years a very common complain has been musicians accidentally bumping their knobs and having to worry about unexpected setting changes. These new rubberized covers cover the shaft and threads to add some resistance when adjusting your settings. Great for touring musicians that don’t want to check each setting every time their gear is carelessly moved by band mates. Also a clean looking alternative to knobs. Compatible with most pedals. These are available by request on any FXdoctor pedals and will be available for order on the website in a few weeks at a price of $0.50 each..

Roland Jet Phaser AP-7



This has been an on going project which I think finally came to an end. It was a distortion/phase pedal but you couldn’t select the effects separately. I added the center switch to control the phaser separate from the distortion. I converted each effect to true bypass and added LEDs. The far right footswitch ramps up or down the rate of the phaser. It’s a great idea but difficult to follow when using live. I installed a white LED that pulses the rate of the phaser for a visual indication. This pedal runs off of two 9V batteries for a +/- setup and had no AC adapter jack. I installed a negative voltage circuit so it can run off of a single battery and then installed a standard 2.1mm barrel jack to be used with any standard power supply. It was a large investment of time but the modifications make it practical for live use..

Ibanez AD-9 Revival


Here’s an excellent example of a well-used Ibanez AD-9. When received the repeat knob was about the break off, the dry signal was cutting out, and the footswitch was intermittent. The owner also requested a true bypass mod which is a bit more complicated by the limited space inside the pedal and the dry output jack (separates the dry and wet signal when used). After some careful planning this thing is better than new..
