I have a marshall jcm 900 dual reverb model 4100 head with a jackson USA soloist (mahogany) with a crunch lab/liquifire combo. Im looking to put either a tube screamer or some type of overdrive in front to boost the amp. Im looking for a more modern sound. Hopefully i can make it happen. Please recommend me a pedal well suited for my amp and guitar. Thinking of the maxon 0d808 or one of the ibanez tube screamers. Any input is greatly appreciated.
