On the jcm900 how do I get a more saturated higher gain sound Would switching the mode to low allow me to crank the amp causing tubes to run hotter with lower volume out put
You turn up the gain to 7 or higher, and lower the master. The tubes won't run hotter, but it will have less loudness. And crank it up as high as you want. Low mode is triode which draws less current and the tube runs cooler.
Thanks I'll give it a try What I have found with this amp is that it sounds best when its dimmed and the tubes are heated was looking for that sound without being dimmed out Also don't know anything about the effects ports does the vr1 pot only work with the effects
Something else I'm wondering about would I benifit from changing ohm settings on amp and what else would need to be done if I changed ohms would I need to rebias amp
It'll give you a much fuller sound. Once you plug in the patch cable, play around with the screw next to the FX loop and turn it to the place where you get the best tone. I think it shines at around the middle position.
If the dimed sound is best, the only way to get it is to use an attenuator, there's a bunch. Alternatively you could use a clean boost pedal out front to drive the preamp harder, but it will only be preamp tube distortion, not power tube distortion like when the amp is cranked. They're both great, but definitely different.
Do I need a stereo or mono patch lead I thought the ports were stereo Also really appreciate the advice if there is any more advice all would be great
Not really. If the attenuator is a professional model ,and matched correctly to the speaker and amp impedance, it should operate as a normal speaker. Operator error is more likely to cause problems, as in: mismatched impedance or bad speaker cables.
So I tried the patch cable last night was happy with how it worked now I want to try an eq and see what that does for me thanks again for the advice from everyone
