Danelectro Spring King mod

Posted by in equipment, mods & repairs, Studio

The Danelectro Spring King is a small spring reverb, but there’s also a slapback delay in it, using a PT2399S chip. Thanks to some documentation on the internet I could easily mod the reverb to control the delay. The idea is to be able to get only the reverb signal if we want, and in a general way to take advantage of the delay by changing the Time and Feedback as we feel.Control Delay Time: Between PIN6 (VCO) and Ground, there’s a CMS resistor „362“ (3,6k). Once it’s taken off…read more

Pearl DRX-1 tune + decay mod triggered by TR-606 (poor man´s Syncussion)

Posted by in equipment, KORN HARDCORE CUSTOMS, mods & repairs, News, Studio

Duration 6h for Mods: 350€ + parts (knobs+housing) + postage (No VAT (small business §19 (1) UStG)) Stereoping pointed out some interesting mods for this VCR-looking analog drum beast. Since I like the idea of saving kits i focussed on parameters like tune and decay for real-time control. Triggering those 5 voices by my modded TR-606 with multiple outputs. Great fun! RENT GEAR HERE: Thx for the nice documentation! http://www.stereoping.com/pearl-drx-1-drumsynth/?lang=en The Pearl DRX-1 has 5 Instruments which can be triggered by drum pads.

Got this earlier version of the RE-201 in a very bad shape. After a lot of hours, it´s alive again. Replaced all pots and connections, recapped the power supply and adjusted the tape transport that caused a lot of issues. thx to Jacob Stoy who borrowed his RE-200 for troubleshooting. check out the „sound on sound“ mod! quite noisy but fun unit!!!           https://youtu.be/VJ9MP76cpNM

Posted by in equipment, KORN HARDCORE CUSTOMS, mods & repairs, News, Studio

Duration 10h for Mods: 700€ + parts (knobs+housing) + postage (No VAT (small business §19 (1) UStG)) https://youtu.be/oc9i99rsAnA Spring 2020 new full length video! Completely reverted the previous work. NOW it feels like my very own 909. Notice that signatures from Jeff Mills and Juan Atkins that i was lucky enough to meet during gigs. So the final list of modifications is almost endless since the great nava extra 9 project and Robin Whittle documented a lot of other stuff that i needed to try out. I was actually ok with it…read more

Korg Polysix repair+mod+MIDI

Posted by in KORN HARDCORE CUSTOMS, mods & repairs, News

Got this baby in very bad nonworking condition. Had to replace the processor board (battery leakage) with a cloned version and to source 12 new SSM chips. It got also MIDI plus an input for using the internal chorus FX now. After cleaning its looking brand new. A nice 5k pot replacing R116 near IC31 will increase the unison detune! http://synthhacker.blogspot.de/2013/04/polysix-adding-detune.html Thx so much to Curetronic.com and Malte Rogacki for helping with the reanimation:)
