Guys, I am new to recording and I was wondering if it is customary to track guitars using the amp's reverb or to do it dry and add your own ambience later? I don't have an outboard reverb but will have access to (ITB) Oxford Reverb and T-racks reverb. I will be trying to track the band in a "live" room (their practice warehouse), however if the room sounds like crap I will try and put the amp in a booth I made and re-track the guitars. Any advise will be well apreicated.
It definitely is all about the sound you want. If you generally want a punchy and clean guitar track with a touch of verb for added depth then I say put it on afterwards so you can experiment with different styles and see which verb best fits your mix. If you're like me however and you do heavily atmospheric music and it's part of your sound (when playing live for example) than by all means record with it on. Sure you can't change it afterwards but it will give better flow to the track as that is the sound you're looking for anyway. It will also save you countless hours going mad trying to find the right verb to fit the taste of the tune afterwards.
For rockabilly you might want to use delay instead of reverb. I'm talking a good strong single-tap slapback, using a delay pedal between the guitar and amp, so the guitarist can get the right sound and vibe upfront.
As stated, go for whatever sounds good. But remember that too much reverb on an amp [or on any source that is so mid-range/mega harmonics laden] can muddy things up quickly. If your guitarist loves it soaked, then 10-20% less from that point will probably record really well. Just use your ears. no rules!
while their seems to be a lot of sentiment about recording with the reverb on for vibe, id advise if you're not super sure and confident about it, then be sure to record a DI track of the guitar for reamping later if you decide the reverb doesnt fit. THis way you can always run it back through the amp with no verb if you want to change the wet/dry mix. watch for phase though.
Almost everyone seems to be confirming what I thought would be best, which is use the amp's own reverb. I guess I just need to watch out not to go overboard. RockManDan, I'm gonna try and put your suggestion to use (great tip) as a safety. Thanks to all for chiming in and helping me out here.
