Hi, thanks for the detailed review and glad that you enjoyed it so much !
The guitar playing is indeed legit, I used my Schecter guitar and my Steinberger basse through my audio interface with NeuralDSP plug-ins to simulate guitar amps (there are tons of effects for various guitar sounds, also a piezo emulation for more acoustic sounds since I didn't carry my acoustic guitar on vacation).
Anyway, thanks for listening and for the comment !
