I assume you mean a classic 1 Spot plus a daisy-chain, as opposed to a 1 Spot Pro with isolated outputs. Yeah, that's basically the case. There's two distinct concepts at work here: ground polarity (negative ground / positive ground), which is determined by circuit topology and (usually) decides which lead of the power supply is also connected to audio ground; and connector polarity (centre-negative / centre-positive), dictates only the physical layout of the power supply connection and (albeit with some limitations) is largely free to be chosen upon the whims of the designer. Pedals with the same ground polarity can be daisy-chained together, using converters to swap the connector polarity if required. Pedals with differing ground polarity cannot be daisy-chained together. Say, for example, you're attempting to power two pedals: one, a 'normal' negative ground pedal, has its ground connected to lead A of the supply; the other, a positive ground pedal, requires reversed polarity so would have lead B connected to its ground. As long as the daisy-chain cable is the only connection between the pedals, everything ought to be fine. However, connecting the grounds of the pedals together in any way — such as would be required to achieve the modest want of actually routing audio between them — will cause a short between the leads A & B of the power supply. The Soul-Bender — being based on a vintage fuzz, using PNP transistors, and lacking an internal voltage inverter — is a positive ground pedal. So, while yes you could theoretically use the converter to power the Soul-Bender, you'd be confined to using exclusively positive ground pedals on the daisy-chain. (That is, unless the only reason you want to power your pedals is to look at their LEDs  ) |

Thank you! Felt like I was going insane for a moment. The person giving the suggestion must have thought I had a 1 Spot Pro.
