OK for its price
By Spielbot
As they say, you get what you pay for. When this guitar effects processor came out, it had to compete with Eleven Rack and Axe FX (neither of which are featured on Vintage Digital, which is very odd). Axe was in a higher price range, while Eleven Rack offered very simple routing options and a very conservative effects arsenal. POD HD, on the other hand, shone with its effects diversity and routing possibilities.
You could build very long effects chains, even including some crazy synth FX models (not available on Axe FX Ultra), if you wanted. Another great advantage was the Line 6 foot controller, which could be easily programmed to control the effects unit. You could even use it to send MIDI CCs to other MIDI-controllable devices using POD’s mediocre MIDI routing options. Unfortunately, the sound is just average.
A plain, flat, cold digital sound. Particularly noteworthy are the integrated reverb effects, which are simply terrible. My old Midiverb II from the 80s sounds significantly better. The rest is usable, but nothing really shines here. Sonically, the Eleven Rack is significantly better. Today I would recommend keeping it around as an FX unit to create some crazy effects like dynamic filters, synths and delays. Or as a two-channel sound card with onboard FX for recording purposes on the go.
