I recently bought a new musicman stingray and while running it through my SWR redhead my amp gets hotter than it ever has before. I play in a cover band so the amp is usually running for about 5 hours straight. I've been playing a p-bass with active EMG pickups but I believe that the signal from the musicman is much hotter. I've tried using the active input on the amp but it does not sound as good as it does running it through the passive/active input. My questions if anyone can help are: 1. If you own a similar setup which input do you use and why? 2. Is the heat generated from the amp a concern?
