Get an Ampeg V4 that still uses 7027A tubes. Mine had the original Magnavox tubes in it and I used it for both the guitar and bass in the Crownes recordings (Crownes is pronounced like “crowns,” it’s the middle English spelling.) You can hear how awesome this amp sounds there. I didn’t use any distortion pedals or anything on the recordings, the guitar is straight into the amp. The best thing about it is you can buy one for around $500.
This amp is a great all-arounder. It takes pedals really well, so if a vintage tone isn’t what you are looking for, you can just use pedals to get the sound you want. It has amazing dynamics and a very good built-in reverb. Oh, and it’s louder than God. If you can’t find one with good original tubes, there are still some places online where you can buy NOS 7027A’s but they can be kind of expensive. The other option is to have a tech mod it to take 6L6’s, but that changes the sound.
