Re: Pedals for fattening sound
	
		
	
	
		
		
			Second guitarist in my band quit and I need to fatten up my sound for live gigs. Esp solos sound thin now that there's no rhythm guitar to back things up.
		
		
	 
Effects aren't going to compensate for the way your band's songs are composed. 
A few ideas for going on as a band with just one guitarist:
1.) Your bassist could play keyboards while you solo, allowing him to cover both bass and chords.
2.) Your bassist could play a 12 or 8 string bass, or play through a pitch shift pedal adding an octave up, to sort of provide something in the frequency range of a rhythm guitar and also the low end. 
3.) You can play the riff you're going to solo over into a looper, then solo over it. You have to figure out how to keep your other band members playing in time to the loop. 
4.) You can recompose your songs, removing the solos and replacing them with instrumental sections ("breakdowns", whatever you want to call them) where instead of soloing, you play a cool and attention-grabbing riff that's different from riffs already used in other parts of the song.
Using a combination of the above ideas in various songs might give the band a really interesting sound.
