Morley Jerry Donahue JD10

The Morley Jerry Donahue JD10 is a multi-function stompbox from Morley that packs several jobs into one enclosure: overdrive, preamp, amp emulator, recording line driver and headphone amp. Rather than being a single-purpose overdrive pedal, it is built to cover a range of roles, from shaping tone in front of an amp to driving a recording rig or headphones directly.¹

What it does

The JD10's functions can be grouped by how a player might use them:

• Overdrive and boost: drive or lift a signal, in the manner of dedicated boost pedals¹
• Preamp: tone shaping duties covered by dedicated preamp pedals¹
• Amp emulator: a stand-in for an amp's character¹
• Recording line driver and headphone amp: feeding a recording setup or headphones without an amp at all¹
• Speaker simulator: shaping the signal to sit like a miked speaker, a role covered by dedicated speaker simulation pedals¹

Among these, the speaker simulator stands out for flexibility. Tommy, who wrote the Pedal of the Day feature on the JD10, noted that "The speaker simulator sounds good even when playing through an amp," meaning it is not limited to direct-recording use.¹

What an owner said

Tommy's write-up on Pedal of the Day, published on 14 May 2014, came from his own long-term use of the pedal. He described the JD10's range plainly: "This pedal can do many things, including recording line driver, amp emulator, overdrive, preamp, and headphone amp."¹

His own playing use leaned on one mode in particular:

On how it holds up against other options, his verdict was that it earns its board space even in a crowded collection¹:
