Members mschafft Posted January 8, 2013 Members Share Posted January 8, 2013 Hi everyone ! I have a stock Johnson Loredo 15R. It sounds alright, but a bit too midrangy and can't get cranked much because it gets really loud with gain and volume at 2 or 3. I once read that changing the stock tube can address these issues but I can't find the link anymore. Do you know what I should order to make it warmer and slightly quieter ? Thanks a lot, have a great day Manny Link to comment Share on other sites More sharing options...
Members Les Paul Lover Posted January 8, 2013 Members Share Posted January 8, 2013 you could to stick a 12at7 or 12au7 in V1 in the preamp.These valves have lower gain, so it will change the point at which you reach a certain volume. It works in some applications and some amps, but in most cases, you're better off how the amp was conceived. 15w valve amp is loud, that's the bottom line.

Members mschafft Posted January 9, 2013 Author Members Share Posted January 9, 2013 Great. Thanks a lot. I'll give them a try and order some off the bay. Any brands you'd recommend? (I'm a complete newbie to tube swapping.) Link to comment Share on other sites More sharing options...
Members Ancient Mariner Posted January 9, 2013 Members Share Posted January 9, 2013 Try JJ - generally pretty good. Also Tesla and ElectroHarmonix. Link to comment Share on other sites More sharing options...
Members onelife Posted January 9, 2013 Members Share Posted January 9, 2013 You may not want to limit your tube swap to V1 - if you replace the other 12AX7 with an AT or even an AU you will get different and possibly quite favorable results as well Link to comment Share on other sites More sharing options...
