Mastered by Tom Waltz


“I've engineered some projects from the Boston/New England area and for my money Waltz Mastering has always come through. I did some looking around when I first needed mastering and this mastering studios name kept coming up, I highly recommend him...”

“My single was played against Coldplay on the radio in the last few days. Not blowing smoke..but mine sounded way way clearer and not uber-compressed. It was mastered by Tom Waltz. Great ME.”

“...The difference between the master and the pre-master is truly amazing. The end-result became 'more musical', 'liquified', 'emitting more goosebumbs'. I did not know that that was possible. It seems the quality has moved up a whole class! I do thank Tom Waltz's craftsmanship and his kit for this!”
