AMZFX - FET Tubes Fuzz

"Another ancient pedal from the boxes in my garage. This one has the same type LMB folded aluminum enclosure. It also uses the cmos switching system with a soft-touch footswitch that has been broken over the years and the top pad is missing. I am not sure what the circuit is in this pedal but I opened it up and took a quick peek inside. I could not get much of a view without removing the pots and jacks, but it looks to be using an opamp and a couple of jfet transistors. The clear finish is dirty just like the previous pedal, and not easily removed or cleaned. The labels appear to be dot-matrix printed on adhesive backed label stock, cut out and then stuck in place. The clearcoat was applied last over the labels and paint. At some point I stole the knobs to be used on some other project."

AMZFX - PRE-AMP

"This is a dual op amp booster that was the predecessor to the dual op amp pcb that I sell on my site. I'm not sure how old it is but it pre-dates the internet! I used this pedal sometimes when playing live. A tap of the footswitch toggles between the two channels that can be set for different gains. The enclosure is a folded sheet-metal aluminum box that was widely available. It is a little large compared to modern pedal builds. The power supply jack is a 3.5mm phone jack style socket, such as was used on the original Rat pedals. The bypass is a soft-touch electronic switch circuit using a cmos chip. This was before microprocessors became very small and cheap, but cd4066 cmos switches cost pennies and were available everywhere."

"Here is a selection of inexpensive enclosures that I bought for future use. Going clockwise from the bottom left are: a 4" electrical box, a 4" PVC drain cap, a 6" aluminum cake pan, a stainless steel bowl, two small lunchboxes, a wooden box and next to the TS-9 are some wooden knobs. The electrical box and drain cap came from Lowes but Home Depot has them as well. I found the steel bowl at Academy Sports in the camping gear section. The cake pan, lunch boxes, knobs and box are from Michaels craft store but Hobby Lobby has similar items."
