The Glockenklang Onboard 3-Band Preamp is a 3-band onboard preamp, featuring transparent and noiseless bass electronics, an active/passive switch, and a 20Hz - 20kHz frequency range. The Glockenklang 3-Band Onboard Preamp is active/passive switchable (at the volume push/pull), has a balance-pot with no volume dip in centre-position, a treble-pot with +/- 18 dB@18 KHz in active mode, acting as classical highcut in passive mode, mid-pot +/- 9 dB@550 Hz and a bass-pot with +/- 14 dB@40 Hz.
