    DEMO Breadboard builds [Tone Reaper //// Boss HM-2, MT-2 + mods /// JCM800 Pedal /// EAE Model feT]

    yeah it's a bit nasty 🥵 oops and at least if you don't like the muff+HM-2 EQ combo, you could try a different distortion front end. maybe a RAT? could be sick. i'm thinking i might try something with a CD4049, maybe a red llama or chuck's CMOS muff tried an SD-1 boost for it, but it just got...

    DEMO Breadboard builds [Tone Reaper //// Boss HM-2, MT-2 + mods /// JCM800 Pedal /// EAE Model feT]

    here’s the russian muff w/ HM-2 EQ: (i maxed the EQ at the start of the demo like a dickhead and it sounds awful but i hope somebody somewhere deep down needed it to happen so i did, but then i dialled it down to sane EQ settings) i only realized upon revisiting this thread that i forgot to...

    Isosceles Boost - No worky

    wicked 🤙 a long long time ago, i had similar results on my isosceles build that worked fine, but i felt it was lacking (TC pre mode was fine, but the fortin 33/grind modes seemed a bit weak/quiet) so i changed R4 from 16K to ~20K. this seemed to improve the levels a bit (although this does...

    hmmm... :unsure: well, time for some pictures...

    Isosceles Boost - No worky

    the only thing stands out to me is how or why the emitter (3) is idling at a higher voltage than the base (2). good question though, wtf is that BC550 doing? seems to be part of some sort of negative feedback mechanism in conjunction with the opamp...

    SOLVED Magnetron resistor (substitution?) question

    if you have x2 10K resistors you can stack them in parallel for an equivalent 5K resistance, which will be a close enough substitution for 4.7K

    DEMO Maxon ST-9 w/ SD-1 inspired mods (AionFX Cirrus)

    hahaha band costume. cheers 🤙🏻 yeah for sure the matte sand finishes are great. pretty stoked about the new range of colours. hope we can get a good yellow one soon. yeah thanks, i’m glad it turned out being a worthwhile experiment, and yep makes a great boost for high gain/metal stuff. they’re...

    DEMO Maxon ST-9 w/ SD-1 inspired mods (AionFX Cirrus)

    around the same time that I had the idea of doing the discrete opamp SD-1 with the Wilhelm Scream PCB, i also pondered similarly about the ST-9 and thought what if, instead of having an ST-9 based around the TS-808/TS-9, why not build one based around Boss SD-1 values instead? initial...

    DEMO Breadboard builds [Tone Reaper //// Boss HM-2, MT-2 + mods /// JCM800 Pedal /// EAE Model feT]

    alright, here it is. finished a HM-2 build on the breadboard this arvo. it's gnarly. gotta do a demo soon. so tonight i plotted out a russian muff on the free space left (minus tone circuit & q4), and got it running into the HM-2 EQ. but it’s 1:45am so i can’t properly test or hear it yet, but...

    Byzantium Flanger - How To Correctly Attach The Stomp Switch (A Build Guide Would Have Helped Immensely)

    so sorry to hear about the passing of your wife. i would absolutely love to help with this, and finish these off. but unfortunately i am too far away in madmaxland for this to be feasible 🫤 and then there's the risk of it going missing in the post

    Byzantium Flanger - How To Correctly Attach The Stomp Switch (A Build Guide Would Have Helped Immensely)

    the key to all of this is to DRY FIT everything (and i mean everything) to ensure fitments etc. before applying solder to anything. (here's a pic where i've checked the fitment of the two boards together with the header pins/sockets already mated together, which is how they should be when you...

    DEMO Breadboard builds [Tone Reaper //// Boss HM-2, MT-2 + mods /// JCM800 Pedal /// EAE Model feT]

    despite claims that the amptweaker tight metal is meant to emulate a 5150, the aionfx version, "ember metal distortion', i built was quite a disappointment. there's definitely better distortions out there. e.g. the brown betty i built was way more fun. [although i reckon the 6 knob version...

    DEMO Breadboard builds [Tone Reaper //// Boss HM-2, MT-2 + mods /// JCM800 Pedal /// EAE Model feT]

    cheers! none of this is really all that serious, (my preferred rig/method is a drive boosted high gain tube amp channel) it's all just a bit of fun and experimentation with the circuit that left a huge impression on me from my youth, by making otherwise awful cheap solid state amps fun and...

    DEMO Breadboard builds [Tone Reaper //// Boss HM-2, MT-2 + mods /// JCM800 Pedal /// EAE Model feT]

    i was considering posting this in the modifications sub-section but im not sure that a couple cap changes is worth a post there. or anywhere really, but i guess this thread will do since the MT-2 is the largest circuit i’ve breadboarded so far. after fixing a few errors, the build sounded...
