Our good mate Shane from IntheBlues Melbourne Australia produces a great JOYO amp sim video here, comparing the tones of three of the Joyo Amplifier Simulation Pedals.
1. American Sound - Based n the 57 Bandmaster and can also sound like other classic Fender amps including the Fender Twin and '65 Deluxe Reverb for example
2. The British Sound - Can replicate the classic sounds of Marshall amps including the JCM900, the Blues Breaker and more.
3. The AC-Tone - AC-30/AC-15 Heaven. These sound like the Classic VOX Amplifiers from clean to stinging and singing lead tones
Check out Shanes awesome video demos online and show your appreciation by giving him the thumbs up:
