alondo1234 Posted October 5, 2010 Share Posted October 5, 2010 Hi Ive got a trace elliot gp12smx pre amp. Im wondering if you could recommend a different pre amp valve? The 1 I currently have, which is the standard fitment, gives a rounder slightly warmer sound (very clean if that makes any sence) which is ok however id like a valve which could colour the sound more to give a rock/heavy rocky vibe, that kind of valve overdrive sound (dirty and distorted). Any suggestions would be welcome. Regards Al Quote Link to comment Share on other sites More sharing options...
Rich Posted October 7, 2010 Share Posted October 7, 2010 Watford Valves have a good range of 12AX7 preamp tubes [url="http://www.watfordvalves.com/products.asp?search=12ax7"]here[/url]. Each one has a brief description of characteristics. [url="http://www.watfordvalves.com/cgi-bin/documents/testreport_2.pdf"]This[/url] is worth a look too.

SS73 Posted October 13, 2010 Share Posted October 13, 2010 To get any versions of your pre amp valves to get dirty you will need to increase your signal, ie turn up the gain, this will also make your original pre valve get dirty, it's then a question of finding the type you like. But don't confuse harsh and brittle over smooth and warm, the former is the nature of all new and Chinese valves which have no depth, find an old Telefunken or Mullard these are smooth but will give more high freq's than any new version.

Better of shoving a valve distortion pedal in the high effect loop, perhaps a DHX would be best! Quote Link to comment Share on other sites More sharing options...
