BF2M is our famous high-impedance input buffer, designed to provide a completely transparent buffering solution to ensure a consistent sound from your guitar.
Our design goal was to retain the sound of your guitar plugged directly into the amp, while providing an interface to additional stomp boxes – without altering your guitar tone or add any noise to the signal chain.
It utilizes two independent buffers with separate inputs and outputs. BF2M is perfect for serving as the first and last unit on any pedalboard.
In systems with multiple stompboxes, additional line drivers may be required for the best performance.
The first buffer converts your high-impedance guitar signal to a low-impedance output, enabling it to drive stompboxes without tonal change or added noise. BF2M is a unity gain buffer.
The second unity gain line driver leads your signal along to your amp. Again, there is no tonal change or noise added to the signal at this stage.

Q: Which power supply would you recommend for the BF2M ?
A: We highly recommend the Cioks power supplies, if you need multiple DC outlets.
Q: Can I use a 12VDC supply ?
A: NO – the BF2M requires a 9VDC supply !!!
Q: Can I use my 9VDC @ 1000mA power supply with the BF2M ?
A: Yes you can. The BF2M requires a minimum of 175mA – so everything higher than 175mA is fine.
Voltage (VDC) should always be precisely what the unit requires.
Current (mA) should be the same or higher as required by the unit.
“BF2M is an essential tool that should be on ANY pedalboard.
It features the Input Buffer and Output Line Driver used in the
Custom Systems that I have built for artists like David Gilmour,
The Edge, MUSE, Steve Morse, Rammstein, Scorpions
… just to name a few.”
