Hi Montrealers, just wanted to give some props to Nicolas at Omnitek. He repaired for me a VERY expensive and powerful head the manufacturer themselves had charged me $200.00 plus shipping to "fix"--obviously, since I then took it to Nicolas, the manufacturer did squat in terms of solving the problem. Nicolas fixed it COMPLETELY in very short time, and only charged me the minimal fee of $52.00. I can't recommend him highly enough. If you are in Montreal, Quebec and have an amp needs fixing, take it to Omnitek.
