Members bluesboy Posted December 14, 2008 Members Share Posted December 14, 2008 has no clean headroom with my bridge pickup. I went back to 498T/490R inmy EPI LP standard, and they sound great, but on the bridge pickup i start to get breakup immidiately, amp volume settings- normal around 3, and master just on for bedroom play. I use this amp for jamming with my buddies and i like to have a somewhat clean sound... any ideas for improving some clean headroom for this amp? Im keeping these pickups in Link to comment Share on other sites More sharing options...
Members crowquill Posted December 14, 2008 Members Share Posted December 14, 2008 turn down the volume on the guitar Link to comment Share on other sites More sharing options...

Members 9ball Posted December 14, 2008 Members Share Posted December 14, 2008 i actually get some great clean/semi clean tones by cranking the amp and turning the guitar volumes down noob :poke: Link to comment Share on other sites More sharing options...
Members crowquill Posted December 14, 2008 Members Share Posted December 14, 2008 You could try swapping one of the preamp's 12ax7 tubes with a 12at7. Swapping it in V1 will have the most effect, V2 less, V3 even less.... etc. Link to comment Share on other sites More sharing options...

Im keeping these pickups inIts not going to magically lose clean headroom from the guitar. It will overdrive with the same amount of signal being sent to it regardless of where the signal comes from. Your LP is obviously sending a stronger signal than the Strat. Thicker and hotter probably. Turn down the gain and roll back the bass a little. Also, as mentioned, don't just blow off the comment about actually using the guitar's volume knobs. It was a great answer. As far as changing tubes, speaker, etc, everything you do is going to also affect your Strat tone too when you use it. Link to comment Share on other sites More sharing options...

Members bdubbs Posted December 14, 2008 Members Share Posted December 14, 2008 I agree with the volume idea. The 498T is a pretty hot pickup at around 13.5k. Link to comment Share on other sites More sharing options...

Either waya higher efficiency speaker will give you the same volume, at a lower setting on the gain/volume knobs. Link to comment Share on other sites More sharing options...

Members OverDriven Posted December 14, 2008 Members Share Posted December 14, 2008 :facepalm: Are you aware that with a higher efficiency speaker, you are buying more clean headroom? Come on man. In this case, the speaker would not help. If the breakup was coming from running the amp at extremely high volumes, then yes a speaker might help. This overdrive is occurring in the preamp, and a speaker is not going to help that. Link to comment Share on other sites More sharing options...

Members tlbonehead Posted December 14, 2008 Members Share Posted December 14, 2008 the speaker will get you more head room if its power amp distortionif its pre amp distortion it wont...can we agree on that?:poke: Certainly not. A lower gain/preamp setting on the amp will give less preamp overdrive/gain/saturation, right? It will also probably lower your overall volume, right? So the added DB of the more efficient speaker brings more volume back in. So, you therefore have the same amount of volume, now with the gain knob setting lower. Lower gain setting on the amp SHOULD = less preamp overdrive. I guess if the gain is set at say 1, and you are still saturating the preamp, then you need to go to a lower V1 if you want to clean it up. Otherwise, if there is room to lower the gain, it will equal less preamp overdrive. That's why amp manufacturers put it there, to control how much gain you want.

Members bluesfralins Posted December 14, 2008 Members Share Posted December 14, 2008 i guess you could lower the bridge pickup but just using your volume knob like everyone else already said, pretty basic Link to comment Share on other sites More sharing options...

Looks like the master is barely on which will give tons of room for for clean-ability. Should have read that more carefully initially. What is "normal" as far as the amp is concerned? If it is the channel volume, the OP should just be able to lower that and bring the master up a bit to compensate. If that doesn't work and he doesn't want to venture off of 10 on the guitar's volume knob, then a 5751 or lower in V1 would work. Or even an EQ pedal in front of the amp with the sliders lowered.
