I have a problem that I can't get the sound I want from Helix using impulse responses. Using hi-gain amp, they sound too "dark". The top highs are missing and there's too much high mids around 2,4kHz. I am using the Own Hammer Diezel IR's, and I did an A/B test using the Poulin LeCab 2 plugin. I load the IR to helix, then load the same IR to lecab and bypass the helix Impulse response block and it sounds much better with lecab. The top end is much clearer and the mids sound much better.
What am I missing here?
