Amplifier Information

The Harmonicaster will work with any instrument amplifier.

Harp players have known for a long time that not every guitar amplifier is suitable for traditional cupped mic harmonica. Because of the everpresent threat of feedback when using a microphone, high gain guitar amps are not really suitable for harmonica.

Harp players have gravitated to a small number of traditional guitar amps, like the Fender Bassman, that work well with cupped mic harp out of the box, guitar amplifiers that have been modified for use with harmonicas (typically by reducing the gain in the preamp stages), or using purpose-built harmonica amps like the Sonny Jr or HarpKing.

In a band setting, a harp player blowing through a lower gain, harp-specific amp might have difficulty cutting through the mix. When it's time for a harmonica solo, a lot of bands have to back off a little on the volume.

That's not a problem with the Harmonicaster, which can play through a 100W Marshall stack without feedback. While it's possible, with ridiculously high gain and overdrive, to create feedback with the Harmonicaster,  under normal playing conditions feedback is not an issue. We test the Harmonicaster using a 50W tube amp with three 10" speakers and a 100W solid state amp with a single 12" driver. On their clean channels you can 'dime' both of those amps, turn up the Harmonicaster's volume control all the way to 10, and still not get any feedback.

The Harmonicaster will sound good with a little 5W valve amp, and it will sound good with a heavy metal monster of an amp.

If  you want to use the Harmonicaster with an amp designed or modified for use with harmonica, we recommend the use of a clean boost pedal between the Harmonicaster and the amplifier, for maximum gain.
