We used the control labels as in the original Fender® 6G15® DWELL: it defines the amount of effect applied to the dry signal. Please notice that each spring reverb pan (what you see underneath the unit) has its own decay value, which means that the time the reverb effect lasts depends on the type of reverb pan that is used. MIXER: it defines the balance between dry and wet signals. The more you set this control low the more the signal remains clean, although you can still hear a reverb tail, especially if the Dwell is set very high. At the opposite, by setting this control high, the signal is in the hands of the unit which changes the sound heavily by making it a bit smoother and affecting the attack of the guitar: like in the original Fender® unit. TONE: it defines how bright or dark the output signal is. Setting this control high makes the tone more trebly, emphasizing the reverb-drip effect, but can also result in a very harsh guitar sound. Please note that the Tone control is post-mixer.
