Bastl Instruments released Buddy

Bastl Instruments released Buddy, a four-channel eurorack stereo mixer optimized for hybrid setups. Channels A and B are optimized for eurorack sources (either mono or stereo) with a slight boost (×2 / +6dB). Channels C and D are line-level pre-amps that can boost the signal up to ×10 / +20dB and feature stereo TRS jack inputs for directly connecting desktop units without further adaptors. All channels feature a clean boost via the high-quality, low-noise NE5532 op-amp (same as on the Dude), which delivers smooth overdrive – that can be used to overdrive clean stereo signals. Several Buddy mixers can be chained via jumper cables on the back to expand the number of channels without losing precious inputs.


  • Channels A and B:
    — DC coupled
    — 100k input impedance
    — gain ×2 / +6dB,
    — left input normalized to right channel
  • Channels C and D:
    — AC coupled
    — 10k input impedance
    — gain ×10 / +20dB
    — stereo TRS 3.5mm jack input or 2× mono TS 3.5mm
    — solder jumpers to convert to DC coupled
    — solder jumpers to normalize left input to right channel
  • Soft Zenner clipping at 10vpp on mixdown stages
  • NE5532 op-amp for low-noise pre-amp
  • 1k output impedance
  • Chaining back jumpers L/R inputs and L/R outputs:
    — Only when Buddy outputs are not patched, the mixdown
    is sent to the output chain jumpers (patch configurable
