The original push-pull tube microamp/DI, our Stomplifier was the subject of a Kickstarter campaign that garnered a lot of attention for us.  Our tonal goals ultimately required custom transformers that wouldn't fit into the Stomplifier's little black box, so we developed our Solitaire 3-tube DI instead. Result: we can now make one or two of our Stomplifier prototypes available for public sale, custom configured for your needs.  XLR and 1/4" outs, instrument and line inputs, switchable tone stack, power from 12VDC external supply (included). Ideal for guitar, harmonica or any other mid-register instruments requiring added warmth and harmonic richness.
