I've got a gig coming up with a fairly successful local band, playing a really good venue and i need to sort out my live sound properly. Essentially at short notice i've been hired to fill the gap as they've been playing with only one guitarist for around 12 months. To introduce me as a new member they want me to play the entirety of a solo to a song they previously shared between two guitarists. This is where my problem has become apparent. As it stands i run a Marshall JCM900 combo amp. Previously to get a volume boost, on cleans i used a compression pedal and to get a lead boost i ran a BOSS Metalcore pedal through the clean channel. This causes a lot of feedback. Running the metalcore on the distorted channel doesn't sound so good so i need to hit two pedals for solos as well. Recently i've been advised that overdrive sounds better than distortion, i play heavy metal (at lamb of god sorts of heavy) and i would have thought overdrive wouldn't cut it for that. I've also been told about noise gates, boost pedals and EQ pedals. I wondered what pedals you guys would say are essential for playing this sort of music live and getting an appropriate boost for solos. I don't necessarily need specific pedals though any that you consider particularly good would be appreciated. Thanks in advance!
