made a short video for those who are still researching... i used a sound level meter to match the volume on both amps, though the ibanez just has a lot more bass, so that might make it seem louder. Fender Blues Jr. Tweed (15w) with a NOS Jensen speaker. All Stock. Ibanez TSA 15w head and cab. I replaced the speaker with a Celestion G12 Vintage 30 and the v1 tube with a JJ 12AT7. All the rest are stock. recorded with an apogee one built-in condenser mic placed at an approx. equal distance from the 2 amps. Guitar PRS hollowbody mccarty.
