Palmer Duetto Nano Mixer – Mint, Boxed & Under Warranty

Palmer DUETTO Nano Mixer in mint condition, both cosmetically and functionally – virtually as new.

Purchased new in December 2025 and still covered by warranty. The original purchase invoice will be provided to the buyer.

I bought it to play together with my son, allowing us to connect two instruments to the same amplifier. It has only been used a couple of times, as my son subsequently stopped playing, so I no longer have any use for it.

The unit is in excellent cosmetic condition and works perfectly.

It currently has Velcro fitted underneath for mounting on a pedalboard. This can easily be removed if not required.

What is the Palmer DUETTO?

The DUETTO is a compact 2-input active mixer designed primarily for electric guitars and other instruments, but it can also handle line-level sources.

It allows two instruments or audio sources to be connected to a single amplifier input, with an independent level control for each source. This makes it particularly useful for:

• Guitar/bass lessons – teacher and student can play through the same amplifier
• Two musicians sharing a single amp or powered speaker
• Combining two instruments or other audio sources into one mono output
• Pedalboard setups requiring two signals to be merged
• Use as a mono summing mixer
• Cable driver
• Recording preamp
