Conspiracy to Commit Electronics Nobelium Preamp 2025 - Candy gold Nobel

Nobelium is a low-noise, high-quality, studio-grade clean tube preamp and D.I. It has a nice wide frequency response to be perfect for bass or guitar, and includes a switchable HPF to cut down on unnecessary rumble.

There is a Unagi transformer for the DI, with a ground lift switch. 

This was assembled by me to a high standard. PCB is from Conspiracy to Commit Electronics. All parts are from Mouser Electronics, Amplified Parts, or Tayda. 

The enclosure is powdercoated with gold candy sparkle metallic, knobs are from Lovemyswitches, and tubes are new 12au7 JJ tubes. I also added a combo “on/off and bypass” switch. This allows the pedal to be turned off and bypassed without unplugging it. Note that this isn’t to be used for on/off use during playing like a footswitch would be, as there is a short delay when it is turned on to power up the tube circuit. 

Please note that this is a high voltage tube amplifier pedal and it should not be opened while plugged in. The only user serviceable part inside is the DI volume which should be adjusted only with the pedal off and unplugged. 

This pedal uses a standard barrel plug power supply and will fit well on your pedalboard!  It needs at least 9v and 650mA to run. 

I can also make these with custom powdercoat, knobs, tubes and LED colors, or add a power or true bypass switch. Please reach out if you want a custom quote.
