Wrote the following about Valeton GP-150 Multi-Effects Processor - NAM & IR Loader

Absoluut een top bakkie, erg toffe versterkermodellen al standaard erin, mooie vette heldere klankkleur in deze hardware, echt weer een heel stuk beter dan de oude GP-100 die ook zeker niet slecht was.

Soms vraag je je af hoe ze die digitale modellen toch weer weten te verbeteren, maar het lukt ze telkens weer om het geluid te verfijnen.
