Vintage RFZ Preamp Racking

Posted by in equipment, mods & repairs, News, rent studio

Those great sounding 70’s preamps from the former GDR broadcasting with discrete design and transformers were found on a local fleamarket.  Now they needed recycled wooden housings (dia boxes) powersupplies und XLR inputs/outputs. Not the most versatile preamp (no low cut,48V) but perfect for dynamic mics. Really pleased with the coloured tone and the huge amplification of 70dB!!

Proco RAT Life turbo ruetz mod

Posted by in equipment, mods & repairs

Modified this little beast of distortion with some new clipping diodes that change the pedal into the Turbo Rat. You can select the stock diodes or disable the whole clipping. 3pedals in one!!! The filter circuit was enhanced by the Ruetz poti that changes the tonal quality a lot. Duration: 1.5h

Boss Chorus Ensemble CE-1 modified

Posted by in equipment, mods & repairs

Fairly simple modification to my favourite chorus device. Its possible to use the depth of the vibrato section for the chorus as well now (or switch it back to original). I can perform this mod for your pedal as well! Please contact me here: www.jacobkorn.de/contact The sound is a dx7 string patch btw. Input impedance mod: Replace the 50k volume pot with a 500k log and for R11 ( 470k) 1M in parallel (=319k).    Duration: 1,5h

Alesis HR-16: custom sound roms

Posted by in equipment, mods & repairs, Studio

Replaced the internal sound eproms of the cheesy sounding machine from 1987. The new roms include 2*48 sounds of Classic drummachines like TR-707, TR-727, 909, Linndrum, DMX, RZ-1 etc. Still needs the overall pitch adjustment mod. Thanks to Alex Erlewein for burning the eproms and the help! more info here: http://www.burnkit2600.com/hr-16/ http://www.vintagesynth.com/misc/hr16.php    

Live Jam with ZAQuencer BCR2000 sequencer

Posted by in equipment, Studio

Being involved in the development of the Zaquencer Firmware in the final stage, he now added it to his arsenal for creating his unique sound: “I already use mostly hardware synths and sequencers, but the Zaquencer still brings something to the table. It´s as fun and intuitive as an oldschool analog sequencer, but it goes much deeper with possibilities if you want it to.” ZAQ audio: https://zaqaudio.com/testimonial
