complicated question my friend. in a nut shell yes. the single will sound real close to the triple but there are many things to consider. how many speakers are you pushing (4x12 or 2x12 or maby 1x12) whats the wattage on the amp. pick ups , strings, guitar. they all make notable changes to your tone. any amp will sound different at louder volumes. whats your favorite tone from your favorite band/album. research what they used to record/play live. you just have to dig a little bit but the info is out there. for me I wanted the lamb of god tone. I got a triple rect and found it was a bit floppy in the low range and not enough sustain on single notes. couldn't get a real tight metal tone out of the box. did some research and got a tube screamer and used and cab with vintage 30's. spent some time tweeking and holy #$%! I nailed it. I am lamb of god now. sound just like there tone. marshall or mesa both great amps. IMHO mesa will give you more options tone wise. every little tweek will go a long way but takes some time to dial it in. I think marshalls are more user friendly but have less tonal range. the single dual or triple all have the same mesa sound but more wattage of the amp will give you more headroom on your eq settings. if your concerned about being to loud to get your tone research iso cabs. I record in my garage about 20 ft from my neighbors bedroom window with a 4x12 mesa cab and I can get great sound out of the triple without any complaints. I use a tube screamer and a compressor and mic the cab into protools. I am very pleased with my mesa.
