RESISTORS: All 1% metal film – NO value substitution here
CAPACITORS: Panasonic solid polymer cap on C!4 A rare NOS Sprague .004uF 1KV Sprague ceramic cap for C10. Two more rare green-colored .05uF NOS ceramic caps for C6 & C9. I had all of these old caps since 1988. All the other caps are 5% WIMAs + a large blue 1% .01uF Vishay box cap on C11.
TRANNIES: All 2N5088
DIODES: I just used two 1N4148
I had to bypass the AMZ Mid / Presence control because I already had this stainless steel enclosure with 3 pre-drilled & straight-aligned pot holes (pretty much looks like a genuine Big Muff) which I scored in eBay about 2 years ago. Ironically, my build is a Triangle variant.
FYI, I use a P-touch 2730, Mac & Win compatible tape printer for the labels, 3M vinyl car wraps for color & aesthetics and a non-polarized & wired LED assembly sold at eBay & made by Alpinetech / Model# PLB-6. I used ribbon cables for the pot connections.
TESTING EQUIPMENTS: Marshall JVM 205H head / Marshall 1960A cab / IBANEZ S5470Q guitar. Jackson Japan-made Warrior guitar with genuine SD Invader humbuckers. Only Halo Fuzz is connected.
TEST RESULTS: As compared to my old BMP, the Halo Fuzz has downright identical smooth fuzz quality but has more headroom, lesser noise interference & a bit more tweakable tone control.
Thanks to Kevin & the AION techies for a better re-design of the famed BMP.
How many BMP variants have you cloned? Build the Halo Fuzz & tell us about it. Thanks for reading!
