Hi Rob, these machines are meant to be on from the start with no mains switch. There are 2 effects the machine can give, echo and a kind of reverb. The swell switch is for the reverb effect. The low volume could due to dried up electrolytic coupling capacitors. Try bridging one at a time with a known good one of similar value to see if any improvement can be had. If this doesn't help then as others have said head gaps and azimuth adjustments may be the cause.
