“I am VERY impressed with the new version; the redesign is highly successful. It sounds great (like a spring “cathedral” reverb, but the spring sound is not overdone; the effect is very smooth…Bottom line: this is not a toy, and does exactly what it is supposed to do. Check out the videos on their website, they don’t lie… I am really impressed with this thing. No electricity, and a very, very nice reverb sound…”

“The ASPRI is a great accessory! I was very pleased with how dramatically it improved the tonal response and volume of my Yamaha FG-400A. It is an OK guitar but doesn’t have much sustain or response to light fingering/touch. The ASPRI has given it a much better voice and touch response, so I’m very pleased with it. Made a dull guitar sound super! Highly recommended.”
– Bil Andersen

“I just bought an ASPRI UNIT – used it on my Blueridge acoustic guitar and… I could hear “heaven”…. Please believe me and try it yourself – you feel like playing in a concerthall ….Great stuff ! Thanks a lot for changing my musical life !”
– Corneille Driezen

“I have applied it to a sort of classical hybrid by Ibanez. It sounds quite amazing, and actually brightens up the guitar’s tone without sacrificing the warmth of the classical aspects of this guitar. I do appreciate very much the engineering that must have gone into getting this right, where right is basically perfection.”
– Vic Von Gemmingen
