{"product_id":"greer-amps-soma-63-vintage-preamp","title":"Greer Amps SOMA 63 Vintage Preamp","description":"\u003cp\u003eA brave new world of tone, the SOMA ‘63 Vintage Preamp is the first pedal in the XFR series of pedals from Greer Amps. The SOMA ’63 is a true vintage preamp, based on the tone and feel of vintage brown era amplifiers from California. This pedal simulates the entire preamp, phase inverter, power section, and even the feel of the vintage 10 inch Utah speakers that were in those famous brown amps. The tone stack is designed to provide a wide and dynamic range of tonal options to the user. The Presence control works with the tone stack, and is designed to be a wide range control, effecting the overall sound of the entire circuit. The SOMA ’63 features a steel core transformer in the audio signal path. The transformer lends to the overall tone shaping of the circuit, and when the gain is pushed hard, especially with higher output pickups, the small steel core transformer will saturate, just like a vintage amplifier. The SOMA ’63 can be used as a tone-shaping preamp, or as an overdrive pedal. There are a wide variety of tones available in the SOMA ’63, so users are encouraged to spend time with the pedal and find the tones that suit their sound.\u003c\/p\u003e\n\u003cp\u003eThe SOMA ‘63 runs off of a standard, negative center pin 9 volt power supply, and can be run off of up to 18 volts. At 9 volts, the SOMA ‘63 will have more grit and texture. At 18 volts, higher headroom, a stiffer response, and less overall grit can be expected. Greer Amps’ 5 year warranty covers manufacturing defects and component failure to the original owner, and does not cover misuse or abuse.\u003c\/p\u003e\n\u003ch2\u003eKey Features:\u003c\/h2\u003e\n\u003cdiv class=\"flex max-w-full flex-col gap-4 grow\"\u003e\n\u003cdiv data-message-author-role=\"assistant\" data-message-id=\"31f5f77a-0a21-4790-908e-f3fe8e185311\" dir=\"auto\" data-message-model-slug=\"gpt-5-3-mini\" class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal outline-none keyboard-focused:focus-ring [.text-message+\u0026amp;]:mt-1\" data-turn-start-message=\"true\" tabindex=\"0\"\u003e\n\u003cdiv class=\"flex w-full flex-col gap-1 empty:hidden\"\u003e\n\u003cdiv class=\"markdown prose dark:prose-invert wrap-break-word w-full light markdown-new-styling\"\u003e\n\u003cul data-start=\"0\" data-end=\"670\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1preyrk\" data-start=\"0\" data-end=\"58\"\u003eVintage brown-era California amplifier preamp simulation\u003c\/li\u003e\n\u003cli data-section-id=\"1wx1k2p\" data-start=\"59\" data-end=\"137\"\u003eModels full signal chain including preamp, phase inverter, and power section\u003c\/li\u003e\n\u003cli data-section-id=\"5z4r78\" data-start=\"138\" data-end=\"199\"\u003eDesigned to replicate feel of vintage 10-inch Utah speakers\u003c\/li\u003e\n\u003cli data-section-id=\"1p9j9k7\" data-start=\"200\" data-end=\"250\"\u003eWide-range tone stack for flexible tonal shaping\u003c\/li\u003e\n\u003cli data-section-id=\"16aviy1\" data-start=\"251\" data-end=\"302\"\u003ePresence control affects overall circuit response\u003c\/li\u003e\n\u003cli data-section-id=\"1ch8fec\" data-start=\"303\" data-end=\"377\"\u003eSteel core transformer in signal path for authentic saturation behaviour\u003c\/li\u003e\n\u003cli data-section-id=\"q1at5q\" data-start=\"378\" data-end=\"448\"\u003eTransformer saturation increases with higher gain and hotter pickups\u003c\/li\u003e\n\u003cli data-section-id=\"1uwswdf\" data-start=\"449\" data-end=\"508\"\u003eFunctions as both tone-shaping preamp and overdrive pedal\u003c\/li\u003e\n\u003cli data-section-id=\"hz13t6\" data-start=\"509\" data-end=\"590\"\u003e9V operation for grit and texture, 18V for higher headroom and tighter response\u003c\/li\u003e\n\u003cli data-section-id=\"4orljc\" data-start=\"591\" data-end=\"670\" data-is-last-node=\"\"\u003eBuilt-in 5-year warranty covering manufacturing defects and component failure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Greer Amps","offers":[{"title":"Default Title","offer_id":44247022796980,"sku":"480566","price":409.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/3537\/2980\/files\/GreerSoma.jpg?v=1781494956","url":"https:\/\/www.turramusic.com.au\/products\/greer-amps-soma-63-vintage-preamp","provider":"Turramurra Music","version":"1.0","type":"link"}
