Hi,
I was given a Shure A15BT, which is used to adapt impedance. https://pubs.shure.com/guide/A15BT/en-US?_gl=1*d0cy6h*_gcl_au*MTM3NTE4MDEyMy4xNzA1NjM4NzEy
With 2 XLR(M & F) to 1/4 TS cables, I built a guitar cable with it.
With the 7500 ohm side coming from the guitar and an overdrive pedal, and the 33,000 ohm side going into the Guitar amp, it sounded louder and with more presence.
The overdrive pedal has a 1k output impedance.
In order to better understand what is happening, id like to ask: am I raising the impedance of the guitar pedal output or lowering the impedance of the guitar amp? Both or neither?
Any initial tips would be useful for me to further investigate, and see how I could best use this item.
Thank you

Its a transformer designed to convert high impedance to low impedance or vice versa. Guitar outputs are very high impedance and expect a suitable high input impedance from the device they connect to - here this is your overdrive pedal. Thereafter everythings fairly low impedance and the transformer is probably only changing the volume and adding a small amount of distortion.
The transformer might be able to adapt from the guitar to a low impedance input, but poorly, you want more like 500k or so for that.
