Question: I'm interested in either the Yamaha THR5A or the THR10C. Can I use either for both electro-acoustic and electric guitars (say with a bit of reverb/chorus)? I see the THR5A has the 'EG CLN' mode - is this for electric guitar? The THR10C has an 'ACO' mode - is this a setting for acoustic guitar?
Can I use normal guitar pedals with the THR amps?
Is the THR5A a better choice if acoustic/clean sound is the primary goal?
That's right; the THR10C focuses on tube amp modelling but does include the 'ACO' setting - this simulates the tone from a studio microphone (either with an electro-acoustic or electric guitar) through an acoustic amp. The 'EG CLN' setting on THR5A models a low-gain, clean tube amp sound (which can be used with electro-acoustic or electric guitar).
It's fine to use pedals with the THR Series (though you do have high quality effects built into each model).
We think that if you're after an amplifier for an electro-acoustic guitar (or an electric guitar always played with a clean tone), the THR5A is your best option.
If you're looking for a good all-round model for both electric and electro-acoustic guitars, try the THR10 v2 - this has a variety of tube amp models as well as clean, acoustic and bass modes.
